To all 'wkome't may concern:

Be it known that we; Lnwls Bmmnn and FRANK Bownngboth citizens ofthe United States of America, residin at Detroit, in the county of We e and tote of Michifan, hsve invente certain newsn'd useful provements in Boiler-Cleaners of which' the following is a specification, re erenoe behed thereinto the accompanying drew in s. i

Phis invention relates to boiler cleaners. and refers more purticularlyto a. constru'o tion in which rotatable nozzles or other blower units are-arranged to blow the soot from the boiler tubes. v i on the objects of the invention are to provi e in a. boiler cleencn-nneutomatic blow-oil anddruina to so construct and err t e blow-oil system that it will prevent $0 operator from leaving the supply valve the blow-off nozzle or drain pipe will be automatically opened when'the nozzles are not in use; to provide a, novel-construction and arrangement of rotatable blower (unit;

to provide improved means for supporting the blower umts; and in generelto" provide a. new and improved construction 0 boiler cleaner of the 'cbsmcter above described. Theinvel'ition also-resides in the novel arrengements and locations of the blower units, particularly with reference to the front water leg of the boiler, and in suchfeatures of construction and arrangements and coinbinntions ofparts as willmore fully hereinafterappear. 1 I In'the'druwm Fi ure 1 is a side elevationhl' view showing 1; e boiler clcuningsystemembodymg our invention; 7 i

is of the horizontal water tube type, there belng a 'lurality of tubes B connected at their on s to front and rear water I 's C and D respectively. The uaper on s of these water legs are connects by the drum E, while the usual vertical bullies F and F are em loyed for compelling the hot gases ironit e firebox G to completely traverse the water tubes.

For cleaning the soot from the water tubes B,we employ a. plurality of blower umts H, H, H, H which are connected b a correspondmg series of branch pipes I, I, I and I wlth the main steam pipe J. The latter near its upper end receives steam from the drum-E an is plrovided with the usunl supply valves J. Iowever in constructions such as above described the op erator is liable to leave this valve J open andsimply close the valves K, K, K and K in the various branch pipes; Should these valves in the branch 1 leak, there is danger that the boiler wil e flooded with water discharging through to blower units, and also the further obgcction that unless the drain valve is left open the water or condensation will collect in the blower system.

In the present construction each of these objections are overcome by the automatic blow ofi or drain-system which is as follows. A drain plige line L is connected b various branches M, M, M to the valves K K=, K Although this connection could be made to the various branch pipes above the valves, either location is satisfactory providing the valve is interosed between the drain pipe connection and the niein steam line. At one end the drain pipe L connects with on automatic type of drain valve L the latter being preferably a. belenced valve which is normally held open by the action of o. light spring L nnd closed whenever there is steam pressure "in'the clrainline L. i

The operation of the eutomatio blow-off s stem, as above-described is as follows.

he main supply valve being opened steam will pass into the main steam pipe and as the valve L is normally 0 sued, the steam will blow ofi through the rain pipe L. If there is on water of condensation in the pipes, it will be forced out through the drain pipe, thus insuring a supply of dry steam to the various blower units H, H H", H". These units are generally 0 erated successive! from the front to t e back so that the b ower H or H being first opened would discharge steam throlpih its nozzle. When however the valve 2 to gather with the other blower unit valves are all closed, this would remove the pressure from'the balanced valve L and allow the latter to automatically open communication to the drain pipe. The same action would take place with each of the other blower units, the arrangement being such that whenever any of the units are in use the drain pipe aconnection will be closed or whenever the blower units are shut off from the main steam line, the latter will be in open connection with the drain pipe. Therefore if the operator neglects to close the valve J when the blower u'nit valves are all closed the steam will. blow off through the drain pipe, calling his attention to the fact that the valve J should be closed it will be noticed that the units ll and H are located directly behind the front water leg. and in case either or both of these units are located in these positions. the following mounting for such units is employed. Di. scribing first, the mounting for the unit H this unit is supported by clips 0 secured by Uholts O to one of the pipes The number and spacing of these cli s will, of course, depend upon the length 0 the blower unit and owing to the closeness of the unit to the firebox, an extension l" of the front supporting wall P is employed for deflecting the heat away from this unit. the con struction of such wall being shown in de tail of Fig. 3.

If the unit H" is employed, a mounting such as shown in connection with the unit ll would be impracticable, owing to the in accessible location of the unit. As shown in 'Fi I, the unit ll is positioned about half way etween the top and bottom rows of the boiler tubes B, and the staggered relation of the latter as shown in Fi 2 prevents a direct support being exten ed downward to the blower unit. To overcome this difficulty a diagonal support Q isemployed which at its upper end is secured by a U- bolt Q and at its lower end is provided with a hook Q which extends beneath and supports the blower unit. It will. of course, be

understood that there are as many of these supports Q, employed as are necessary to properly support the blower unit H". oreover, while this type of support is particularly adapted to a unit located in the position of the unit 11 it. is not necessarily limited to such use. i

At their outer ends-the various units are provided with the usiui'lopera'ting wheels or sprockets R. The latter are fixed to the re tatable nozzle pipes S, an extension of which pipe extends nto a head S on the gooseneck S For preventing longitudinal movement of the nozzle, it is provided with a flange R against which rests a brass ring T uion the opposite side of which is a packing R. or preventing the escape of steam at the joint between the rotatable. pipe and the head S, the packing R is clamped between the ring T and the circular flange U on the packing gland l The latter is secured to the head S by locking bolts or screws V which can be adjusted to advance the gland toward or from the header whenever necessary. The usual. sup porting bracket W is employed for fastening the unit to the casing W. The invention however is not limited to the details of construction shown and described except as specified in the appended claims.

\Vhat we claim as our invention is.
